甲硫氨酸席夫碱铜、锌、钴配合物合成及抗O^._2性能

Synthesis of Transition Metal Methionine Schiff Base Complexes and The O_2~·-Scavenging Property

合成了邻香草醛甲硫氨酸席夫碱及其铜、锌、钴等配合物 ,通过元素分析、摩尔电导、红外光谱、电子光谱、热分析及电子顺磁共振等手段对它们进行了表征 ,并用 EPR法探讨了它们对O· -2 的清除作用 .结果表明 ,配体与配合物均具有抗 O· -2 性能 ,配合物清除能力比配体强 。

Some Schiff base complexes:Na[CuLAc]·3/2H 2O, Na[ZnLAc]·3/2H 2O, Na[CoLAc]·3/2H 2O, where L=methionine-o-vaniline Schiff base, have been synthesized and characterized by elemental analysis, molar conductance , thermal analysis, infrared spectrum, electronic spectrum and EPR spectrum measurements. Properties of NaHL and the complexes in scavenging O. ·- 2 have been investigated.
